- BROGKTON, MASSACHUSETTS cHANivnmne MACHINE Application filed December4,1930. SerialNo. 500,110.

The invention has relation to channeling machines, such as that shown inthe patent to Meyer No. 984,773, dated February 21, 1911.

In making shoes for wearers having flat feet it is common to provide aninsole having a wing shaped shank portion thewing or Wings of which areturned against the sides of the last when the shoe is assembled, andafter lasting, are held in such upturned position where they act as anarch support for I the foot of the wearer. To show this, reference ismade to the patent to Orr, No. 1,482,- 140, dated January 29, 1924.

In this patent to Orr, the shank portion of the insole including thearch support wings is wider than the forepart and a special edge gage isnecessarily used, and it is an object of the present invention to avoidthe necessity for using a special edge gage for the purpose ofchanneling arch support insoles.

Also, it is necessary to bevel out these arch support wings by hand orto use a separate machine for the purpose, and it is another object ofthe invention to adapt the'machine of the said Meyer patent to bevel cutthe arch support wings of the insoles. Other objects and advantages willhereinafter appear.

The invention consists in the novel construction and combinations ofparts as set forth in the appended claims.

In the accompanying drawings illustrating an embodiment of theinvention:

Figure 1 is a plan view of the invention as applied, partly in section.

Figure 2 is aside view of the same partly broken away. I

Figure 3 is a detail side view, partly in section, showing the outsideknife in operation. Figure 4 is a similar view of a modification. Figure5 is a detail planviewof the insole. Figure 6 is a fragmentary side viewof the edge slitting knife in operation upon the insole.

Figure 7 is a plan view of the same. In these drawings, the numeral 1designates the channeling or inside knife, of the usual character, andwhich cuts and turns up the flap 2. The knife is mounted in a groove ina knife block 3, being held therein in the customary manner and providedwith the usual adjustment means.

The edge slitting or outside knife 4 has a rectangular shank fitting ina groove in a knife block 5, being fixed therein also in the customarymanner and provided with the usual adjustment means. A presser foot 6serves to limit the depth to which the knives enter the work and ismounted upon the knife carrier. The adjustment means provides forhorizontal adjustment to vary the distance between the presser foot andthe knives. The connection of the presser foot with its block permitsvertical adjustment of the presser foot to'vary the depth of the cutsproduced by the knives.

The work support or table 7 is mounted upon a stem 8 which is rotatablymounted in a vertical slide. The distance of the lip from theedge of theinsole is determined by the edgegage 10 of the usual character as shownin said patent to Meyer, to which reference is made for the mainconstructional features of the machine. I

I In the present case, the table or work support 7 is provided with adished upper surface, the central circular portion 11 of'which is flat,and the annular marginal p0rtion12 of which is inclined, the entiredished surface being similar to that of an ordinary saucer exceptingthat the inclined annular portion is straight in cross section. V

The insole 13 is provided with a single arch support wing 14, and theshank portion of the insole measured across said wing'is somewhatnarrower than the forepart, whereby the ordinary edge gage may beemployed, thereby avoiding necessity for a special edge gage as in thesaid patent to Orr.

The insole rests upon the work support or table and the edge gage actsas a stop to determine its position on the table as customary. Theposition of the edge gage is determined by the lever 106, under controlof the opera tor. The work support being lowered and the insole placedthereon between the same and the presser foot, until it comes in contactwith theedge, the work support is then allowed to rise and the operatorguides the blank as it is fed through the machine. At

' the lip the junctures between the shank and the inside and the outsideof the forepart of the insole the operator moves the hand lever 106 tovary the width of the margin as required.

The edge gage is controlled by the operator to provide the marginal archsupport wing 14 of the insole, which is possible in this case due to thefact that the insole at the shank part across the arch support wing isnarrower than the forepart.

The operator guides the insole so that at the time the arch support wing14 is reached by the edge slitting or outer knife, the main or shankpart of the insole will restupon the central fiat portion 11 of the Worktable, whereas the arch support wing 14: will rest upon the beveledouter part of the table, thereby giving said arch support wing an upwardincline.

In this way about one half of the Wing 14- will project above the top orouter edge of the table 7, and it is an object of the invention aspreviously explained to cut off this upper half of the arch support wing14 or to bevel said wing, by an adaptation of the edge slitting knife f,in combination with the special form of table used herein. For thispurpose the edge sliting knife 4: is provided with an outer extensionknife 15, in line with the usual edge slitting portion 16' of saidknife.

In order to temporarily maintain the outside lip 17 of the insole invertical turned up position, a lip guard 17 is provided, being attachedto the shank 20 of the edge slitting knife at 18.

In making of insoles by the Goodyear method, the arch support wing 14 isomitted, that is to say the operator guides the insole to omit the archsupport wing, and in order to turn the outside lip 17 of the insole overand downwardly to horizontal position, the lip uard 19 is provided insubstitution for guard 17 above referred to, being attached in the samemanner to the shank 20 at 18.

The shank 20 is provided witha lower cutting edge 21, and a blade 22extending laterally of the shank at both sides thereof and provided withthe longitudinal cutting edges 15 and 16 aforesaid, and which arelocated at approximately right angles to the shank, see Figures 3 and 1.This shank 20 has its lower portion for a distance equal to the breadthof the blade 22 provided with opposite curved diversely beveled surfacesleading away from the shank cutting edge 21 and intersecting the uppersurfaces of said blade at about right angles, to thereby gradually turnthe outside lip of the insole, after said lip is cut or formed by knifeedges 16 and 21, about forty-five degrees upwardly and at the same timeresist any downward and inward or reverse movement of said lip.

I claim 1. In a channeling machine, provided with an edge slitting knifehaving a shank provided with a lower cutting edge and a blade extendinglaterally of the shank at both sides thereof and provided with alongitudinal cutting edge also at both sides of the shank, said shankhaving its lower portion for a distance about equal to the breadth ofsaid blade provided with opposite curved diversely beveled surfacesleading away from the shank cutting edge and intersecting the uppersurface of said blade at about right angles, to thereby gradually turnthe outside lip of the insole to about forty-five degrees upwardly andat the same time resist any clownyvard and inward reverse movement ofsaid 2. In a channeling machine, provided with an edge slitting knifehaving a shank provided with a lower cutting edge and a blade extendinglaterally of the shank atvboth sides thereof and provided with alongitudinal cutting edge also at both sides of the shank, said shankhaving its lower portion for a distance equal to the breadth of the saidblade provided with opposite curved diversely beveled surfaces leadingaway from the shank cutting edge and intersecting the upper surface ofsaid blade at about right angles, and a lateral downwardly extending lipguard attachment carried by said shank in rear of and spaced from saidblade and engaging said outside lip to complete the turning thereof tovertical position. 7

3. In a channeling machine, provided with an edge slitting knife havinga shank provided with a lower cutting edge and a blade extendinglaterally of the shank at both sides thereof and provided with alongitudinal cutting edge also at bothsides of the shank, said shankhaving its lower portion for a distance equal to the breadth of saidblade provided with opposite curved div-ersely beveled surfaces leadingaway from the shank cutting edge and intersecting the upper surface ofsaid blade at about right angles, and a lateral downwardly and latorallyextending lip guard attachment carried by said shank in rear of andspaced from said blade and engaging the outside lip to complete theturning thereof to vertical position and turn it farther over anddownwardly to horizontal posit-ion.
